BACKGROUND: The effect of heat stress on physiologicalparameters has been well documented. However, there arereports of a genetic based heat tolerance in some sheep breeds.OBJECTIVES: The aim of the present study was to monitor thephysiological responses of an Iranian fat-tailed breed againstheat stress and an acute stress insult. METHODS:Atotal numberof 15 fall-born ram lambs were selected and...

Dispersal has long been recognized as a crucial factor affecting population dynamics. Several studies on long-distance dispersal revealed a peculiarity now widely known as a problem of "fat tail": instead of the rate of decay in the population density over large distances being described by a normal distribution, which is apparently predicted by the standard diffusion approach, field data often...

The identification of meat quality characteristics from selected breeds grazing in specific regions is particularly relevant to achieve a marketing advantage. Longisimus thoracis at lumborum (LTL) from the indigenous Western Balkan (WB) sheep VlašićkaPramenka (VP) sheep and lambs, and Pivska Pramenka (PP) sheep grazing in Bosnia & Herzegovina (B&H) and Montenegro (MN), respectively, was compare...

The apolipoprotein A-V (APOA5) gene is a candidate that plays an important role in carcass characteristics and lamb quality. This study aimed to association polymorphism of the APOA5 with quality sheep. breed sheep were used 100 consisting Thin Tailed Sheep (TTS) (n=55), Compass Agrinac (CAS) (n=10), Garut (GS) (n=18), Composite (GCS) (n=8), Barbados cross (BCS) (n=9). Identification was perfor...

For the consumer, tenderness, juiciness and flavour are often described as the most important factors for meat eating quality, all of which have a close association with intramuscular fat (IMF). X-ray computed tomography (CT) can measure fat, muscle and bone volumes and weights, in vivo in sheep and CT predictions of carcass composition have been used in UK sheep breeding programmes over the la...

This paper considers dynamic asset allocation in a mean versus downside-risk framework. We derive closed-form solutions for the optimal portfolio weights when returns are lognormally distributed. Moreover, we study the impact of skewed and fat-tailed return distributions. We nd that the optimal fraction invested in stocks is V-shaped: at low and high levels of wealth the investor increases the ...

Forage halophytes such as saltbush (Atriplex spp.) are widely used to revegetate Australian saline land and can provide a medium-quality fodder source. An animal house experiment was conducted to investigate differences in the carcass and eating quality of sheep ingesting saltbush from saline land in combination with a barley supplement. Twenty-six merino hoggets (two groups of 13) were fed eit...
